Skills

Rust, Ruby, Rails, Python, TypeScript, Next.js, PostgreSQL, Neo4j, Redis, WASM, RAG, LLM Orchestration

Built composable AI agent platform replacing human-powered workforce operations, reducing merchant data processing from hours to under 2 minutes
Designed hybrid document retrieval combining BM25 lexical search with Voyage embeddings; researched and deployed self-managed OCR pipeline using SOTA vision models
Redesigned agent orchestration around minimal LLM task decomposition, improving output determinism and debuggability
Developed agentic codegen pipeline to generate reusable WASM artifacts for tool calling in sandboxed runtimes, reducing token spend and increasing execution determinism
Implemented RAG evaluation framework measuring page-level retrieval accuracy and top-k precision against Vectara benchmarks

Spearheading internal AI application development to model domain knowledge using Neo4j-based knowledge graphs
Enabling 24/7 access to technical and business context across the firm through graph-integrated generative models

Developed systems to automate ingestion of corporate actions (e.g., stock buybacks, dividends) into BNY's proprietary platform, Eagle

Dockerized Ruby on Rails backend to streamline development and deployment
Enhanced CI/CD: integrated automated browser testing with GitHub Actions; surfaced test results alongside feature environment links with auto-comments

Email classification pipeline for M&A deal tracking in financial services.

Rust core for high-performance email ingestion and orchestration
LLM-powered classification of deal communications (NDAs, IOIs, diligence requests)
Neo4j knowledge graph connecting emails to deals, parties, and deal stages

Production company portfolio website built with Sanity's headless CMS and reduxjs/toolkit's latest api.

Sanity's CMS gives the client an easy and convenient way to manage what's on their webpage with no compromise on the speed of the site itself

Hook arbitrary bash scripts into io events at a given directory.

Built a multithreaded Rust app that hooks filesystem events to execute bash scripts, practicing memory-safe design without garbage collectors
